The lack of reality you consistently display in your posts regarding efficiency is strange. You seem to expect to get the same efficiency regardless of how you drive. Your posts appear to state that I have 620 HP, I want to use that to the utmost, accelerate as quickly as I want, go as fast as I want AND get the EPA rated range/efficiency. No one promised that.
The example should be:
I buy a 5 pound bag of potatoes. I use it as a substitute medicine ball. I eliminate the damaged potatoes which yields 3 lbs and complain that I didn't get a 5 lb yield.
Conclusion of posters: If I buy the 5 lb bag and use it immediately and as intended, I get a yield close to 5 lbs but if I enthusiastically handle the potatoes, my yield may be less"
To get maximum range, you have to drive like
@GEWC - accelerate slowly and cap max speed - like the EPA test. It isn't reasonable to expect to get the same results with a different driving style.
I disagree. Didn't the chart show miles and kwh consumed? So they didn't use the car's estimation of efficiency. Whether car accurately reflected kwh consumed could be up for debate but they didn't rely on the avg consumption algorithm - at least that's my assumption from the chart.
But I totally agree about mileage potentially impacting range. There's also manufacturing tolerances. Did
@GEWC get the "perfect" car and combining that with her conservative style gets her outstanding efficiency numbers? Am I going to get one that is on the sloppy end of the acceptable tolerance range or will it average out?
